Media Tip: Microparticles show ability to turn in reverse, paving the way for microfluidic devices

Rotating microparticles in a fluid can reverse direction when an electric stimulus is interrupted and then reapplied with the same orientation, forming a self-organized vortex. This research offers potential inspiration for pumps in microsized channels that allow precise fluid delivery for biomedical, chemical and electronics applications.
